What is a requirement for the EML (Email Address) Field?

In the context of the Email Address Field, the correct requirement is that it must be unique. This means that each email address entered into the system needs to be distinct from others to prevent confusion and to ensure proper identification of users. Unique email addresses allow for efficient communication and data management within the system, as they link directly to a specific user.

While options discussing the presence of periods or the verification by a supervisor may reflect concerns regarding formatting or validation, and including a user's full name may have merits in terms of user identification, the uniqueness of the email address is critical in ensuring there's no overlap or duplication that could lead to errors or miscommunication. Thus, ensuring that each email address is unique is essential for maintaining the integrity of the data within the Indiana Data and Communications System.
